You can store many vegetables without refrigeration for a week to a month or more, depending on the vegetable and how you handle it. Carrots, cabbage, peppers, potatoes, onions, and more all do well at room temperature with a little care.
This guide covers the most common ones: how long each lasts and exactly how to store it. It’s useful whether you’re camping, on a boat, in an RV, or just trying to free up space in a crowded fridge.
Start at the Store: How to Buy Vegetables for Longer Storage
Making produce last without refrigeration starts before you ever get home. This part is easy to overlook, but it’s where long storage is won or lost.
Buy never-refrigerated vegetables if you can. Farmer’s markets and produce stands are your best bet. Once a vegetable has been refrigerated, it has a shorter life once it warms back up, because condensation forms as it does. The storage times below assume never-refrigerated produce. Refrigerated produce still works; just plan to use it sooner.
Be picky. Go through items individually and turn down anything bruised, overripe, or with insect holes. Only the freshest, most perfect vegetables will make it through a long stretch without refrigeration.
Don’t buy more than you have room for. Overstuffed storage means bruising, and bruising means rot. Be realistic about your space before you load up.
Transport gently. A bruised spot starts to rot almost immediately and spreads. Use tote bags rather than plastic, put the sturdiest vegetables on the bottom, and don’t overstuff.
To Wash or Not to Wash
There are two schools of thought here.
Washing before storage means everything is ready to use when you want it. The argument against it is that produce lasts longest with the least handling.
In practice, I wash my vegetables before storing them whether they’re going in the refrigerator or not. The key is getting them completely dry before putting them away, because damp vegetables rot rather than keep. As you work through them, you’ll almost always find a piece or two that needs to go straight into that night’s dinner, which is useful to know right away.
Storage Basics
Storage areas need to be well-ventilated, dry, and as dark as possible.
Bins with solid bottoms and ventilated sides work well in any setting. A solid bottom contains the mess if something does rot. Don’t use plastic lids: a light towel or rag laid over the top gives much better ventilation and lets you fit more in the bin. Gear hammocks are good on a boat as long as they’re padded and hung where they won’t bang into anything.
Avoid plastic bags entirely. They trap moisture and the food rots. I’ve tried the green bags marketed for produce and had the same results.
Check your produce every day. If something is bruised, move it to the top of the menu. Anything that’s started to rot needs to come out immediately, and wipe the container with a dilute bleach solution so it doesn’t spread. If you see fruit flies, check everything extra carefully, since bugs are drawn to produce that’s bruised or spoiling.
The same buying, drying, and daily-check habits apply to fruit. I cover that separately in Storing Fruit without Refrigeration.
Storage Tips for Specific Vegetables
Carrots keep one to two weeks, often more. They’ll last a few days with no special treatment, but for longer storage wrap them loosely in aluminum foil, leaving the ends open so moisture can escape, or wrap them in a slightly damp tea towel. If they dry out and look wilted, stand them in a glass of water for half an hour or so to bring back the crunch. The water doesn’t need to be cold, despite what you may have been taught.
Lettuce is the hard case: it really does need refrigeration. It bruises extremely easily while traveling, even chilled in a cooler, and bruised leaves rot fast. Eat it within a day or two of buying. Whole romaine leaves or full heads sold in plastic boxes last a bit longer than loose or picked greens. For a little more life, you can stand whole heads stem-down in a bucket with a few inches of water and a light cloth over the top, which can stretch them to four or five days. This is also why cabbage, further down, becomes the salad staple once lettuce is gone.
Broccoli lasts about a week, but only if it’s never been refrigerated. Once it’s been chilled and taken back out, it spoils in a day or two, because you can’t get all the nooks and crannies dry of condensation. Don’t wash until you’re ready to use it. It may yellow a little; just cut the discolored parts off. If it’s less than perfect, use it in a cooked dish where it won’t be noticeable.
Cauliflower keeps the same way as broccoli, about a week, and with the same catch: only if it’s never been chilled. Don’t wash until you’re ready to use it. Cauliflower may get some black spots over time. Cut those off and use the rest, in a cooked dish if it’s looking less than perfect.
Cabbage lasts a month or more, which makes it one of the most valuable vegetables you can carry. Store the whole head somewhere dry and ventilated where it won’t get bumped. It does fine left on its own; just keep it out of plastic, which traps moisture and causes rot. Peel off outer leaves as they dry or tire, and if the cut edge develops black spots, slice a thin piece off and use the rest. Because lettuce barely keeps at all without refrigeration, cabbage becomes the salad staple. I’ve written a full guide on how long cabbage lasts without refrigeration, including its nutrition value on long trips and how to crisp it back up if it goes limp.
Summer squash and zucchini last ten days or sometimes longer, and smaller ones keep much better than large. If they start to wilt, use them in a cooked dish instead of raw and you won’t notice the difference.
Cucumbers last up to a week uncut, between about 40°F and 68°F, wrapped tightly in plastic wrap and protected from bruising. The warmer it gets, the shorter that window, even when wrapped. Once cut, use them within a day or two.
Celery stores exactly like carrots: wrapped loosely in foil with the ends open, or in a damp tea towel. It’s a little more temperamental, so plan to use it within a week to ten days. Limp celery crisps right back up with a soak in water, the same as carrots. For the full breakdown, I’ve written a separate piece on how to store celery.
Peppers: Whole bell peppers last at least a week if padded well so they don’t bruise, but once cut they go fast, so use any leftover within a day and trim the cut edges before using again. Mini sweet peppers are the better choice without refrigeration, since you can use a whole one at a time. They last ten days to three weeks kept cool and protected from bruising. Leave them in the bag they come in, which has holes to let condensation escape. They may look a little wilted after ten days but still taste fine, and work especially well in cooked dishes at that point.
Tomatoes keep up to about two weeks if you buy them at varying stages of ripeness, from fully green to ripe, depending on when you want to eat them. Fully green ones take roughly two weeks to ripen; partially ripe ones less. Store the not-yet-ready ones in the dark, wrapped in newspaper or paper towels, or in a tube sock with the greenest one pushed in first and progressively riper ones behind it, so you can pull from the open end as they’re ready. Check daily, unwrap when ripe, and eat within two days of full ripeness. Don’t refrigerate tomatoes; cold dulls their flavor.
Potatoes are one of the longest-lasting vegetables: two to three months in cool climates, about a month in the tropics. Store them somewhere cool, dry, and dark so they don’t turn green. A towel over the bin works; a plastic bag doesn’t, because condensation forms and they rot. Keep them away from onions, and avoid wire baskets that create bruising pressure points. If a potato turns greenish, peel that part away before using. If one goes slightly soft or spongy but isn’t rotten, it’s just dried out and will rehydrate as it cooks.
Onions keep best in a dark, dry area so they don’t sprout. One popular method is to put them in pantyhose with a knot tied between each one, then cut them apart as you need them. You can also store them in a ventilated bin with a cloth over the top, never plastic over the top. Don’t store onions and potatoes together, or the potatoes will sprout.
Avocados bruise easily and need careful handling to last beyond a day. The best method I’ve found is to put them in tube socks, then in a gear hammock or bin on top of padding over sturdy produce like potatoes or onions. Buy them at varying stages of ripeness, some still rock-hard, and you can enjoy them over a week or more. Once one is fully ripe, eat it within a day. Expect about one in four to bruise badly enough to be inedible, and don’t try to save part of a cut avocado without refrigeration.
Garlic lasts months in a cool, dry, ventilated spot. It doesn’t need to be kept dark, but keep it out of plastic or anything that traps moisture, which makes it sprout or rot. At a farmer’s market, look for cured garlic with dry, brown, or fallen-off tops. Green tops mean it isn’t fully cured and will only last a few weeks.
Green onions, scallions, and leeks store like cut flowers: stand them in a glass of water. Change the water every few days and don’t be surprised if they keep growing. If you use only the green tops, put the white root ends back in the water and the tops will grow back several times. If your water smells of chlorine, let the glass sit a few hours before adding them.
Mushrooms are unpredictable: sometimes they keep well, sometimes not, for no obvious reason. Don’t wash them until you’re ready to use them. To store without a cooler, take them out of the package and spread them no more than two deep in a flat, uncovered container in a very well-ventilated spot. They’ll dry out day by day but stay good for cooking, sometimes for a month or more. Turn them every day or two so they dry evenly. Use dried ones in cooking rather than raw, and toss any that turn slimy.
Take the Guesswork Out of Your Next Trip
This article covers the vegetables most people ask about. My book covers the rest.
Storing Food Without Refrigeration includes a “shortest to longest lasting” table for dozens of fruits and vegetables, so you can plan exactly what to eat first and what to save for the end of a trip. It goes well beyond produce too: eggs, butter, milk, cheese, sour cream, condiments, and meat all keep far longer than you’d expect without refrigeration when you handle them right. You’ll also find 60+ meal ideas and a four-day sample meal plan.
It’s a practical tool worth reading before you head out and referring back to when you have a question.

Bruce Bibee says
OK, same stupid question – can stuff be rinsed in clean sea water (ie, not from a marina or harbor). It would seem like this would save fresh water and be doubly effective on possible pathogens as they have never been in contact with salt water before.
Carolyn Shearlock says
Bruce —
I’ve never tried it and I wouldn’t.
Basically, I’ll give the same answer I always do when you suggest using sea water — I really hate to say it, because I love the oceans, but I don’t think there is such a thing as “clean sea water” — look at the huge islands of plastic out in the Pacific and so forth. Lots of contaminants make their way into the oceans, unfortunately.
Even if it were “clean,” sea water naturally contains lots of microorganisms that will get on your food and then start multiplying. Dunk a rag into sea water and set it out — it’s going to get very nasty in a few days! Do you want that to happen to your food?
And with the salt in the water, you can’t get the veggies to dry out totally before putting them away — and damp food rots.

Suzanne C says
Rinsing fruit and veggies in a mixture of white vinegar and water seems to make them last a whole lot longer. I initially tried this with raspberries and have continued to do the same solution with all my fruits and veggies before storing and have noticed a significant life span increase.
Monique Davis says
May I ask the ratio of vinegar and water? We are about to push off on a five month journey and I would love to be able to extend the life of my produce.
Thank you!

Suzanne C says
Monique, honestly I have no idea. I just fill the sink up with water and dump a bunch of vinegar in. Guessing, I would say a 1 to 10 mixture. Sorry I can’t be more precise but I was never one to measure things – I just eyeball it.
Jeff says
Monique and Suzanne.
Suzanne is spot on. a mixture of 1 to 10 is fine. No more molding raspberries, rotting strawberries and the like. I believe the same mixture could be used for almost amy “cleaning” of any food stuff. The acid in the vinegar kills off lots of spoors. What has worked best for me is a small bowl filled about 1/2 way with water. About an eighth of a cup of vinegar and then dump in the berries. Swish them around and then I put them back into their “vented” plastic containers. they dry well, don’t mold, and you can’t taste the vinegar either.
JB says
I keep a spray bottle handy that contains a 50/50 mix of water and white vinegar in the kitchen and use it on everything (Counters, cutting boards, fruits and veggies).
Michelle Rene says
Great details!
Rory Finneren says
Great info on here! Kara
Jason Gard says
Kinchie Pan we may have to get rid of the fridge!!
Liz says
If u wash lettuce in cold water and dry well in a salad spinner and then store it in a plastic airtight container it will last at least a week, and still be crisp… it works every time. 🙂
Carla Pretorius says
Put some paper towel at the bottom it lasts even longer!
Deanna Roozendaal says
Finding fresh veggies is often the greater issue, here in the South Pacific. Are they plentiful where you’re sailing, Carolyn?
The Boat Galley says
Not here in the Bahamas, but when we were in the Sea of Cortez, they were fantastic.
Janet Burch says
What about fruit flies? I had tomatoes out on the counter as usual but within a few days the little monsters showed up. I HATE to put tomatoes into the refrigerator but also hate fruit flies. We are in Maine.
Carolyn Shearlock says
I’ve only had problems with fruit flies when I’ve had some blemished tomatoes or ones with split skin. If I notice fruit flies I carefully check over all my produce and usually find something that’s attracting them.
el says
Quit simple. Put some oil in a saucer and a bit of red wine in the middle and the flies commit suicide.
Dave Skolnick says
I have a separate issue: remembering what I have. *grin* CRS. Accordingly, I’ll often keep veg, especially veg approaching end of life, in a basket on the counter. This is entirely to keep them in front of my face so I’ll use them.
Claire Bradley says
Another way of storing carrots, beetroot, celeriac, swedes, turnips and winter radishes is to store them in sand. To prevent shrivelling in vegetables which lose moisture such as carrots, celeriac, swedes and beetroot, store the roots in layers of moist sand or peat-substitute in boxes, in a frost-free, dark place such as a shed or cellar. I tried storing carrots in sand one winter and they kept for absolutely ages (months). No idea if it would work on a yacht but might be worth a try. Given that boats are quite moist places anyway, I would just put them in sand, and let the sand absorb the moisture on the boat, and keep your veg plump at the same time.
Josh Wilkinson says
I’ve read most of the vegetables we refrigerate don’t even need to be refrigerated and will actually last longer not being refrigerated.
The Boat Galley says
Generally, they take a bit of special attention but yes, some do last far longer without refrigeration.
Becky says
Someone noted that since grocery stores need to store their veggies in a way that will make them last as long as possible, next time you buy them, look at how THEY display them. –I’ve kept my tomatoes out of the fridge, and will now try to re-train myself to keep the broccoli and other veggies out of the fridge too—but it will be hard to break myself of that habit!
Ari says
This is tricky because a lot of the big chains put the produce back in fridges at the end of the day, no?
Also in tropical climates grocery stores might be fully air-conditioned and a bit cooler than your boat/counter
Paul Truscott says
You mention not storing Onions and Potatoes ‘together. Do you mean not in the same bag or not in the same food hammock? We have been storing them in separate bags but in the same hammock without issue so far (but then we don’t have large amounts so they get used up pretty quickly).
The Boat Galley says
The closer they are together, the more problems. I try to keep them in separate bins, but if that can’t work, keeping them apart in the hammock — say at opposite ends — will do better than if they’re next to each other. Sometimes, it just comes down to available space — and yes, the problem is worse if you’re trying to keep them for several weeks to months as both onions and potatoes are some of the longest-lasting “fresh” produce for long passages.
Renee says
I would like to know how to keep squash fresh? I never have good luck with lettuce, what are some ideas. I have considered putting ice blocks in the bottom of the cooler and then putting a layer of bubble wrap to keep the vegetables from laying right on top of the ice, has any one ever tried this. We are going to Lake Powell the coolers are kept inside but we still have a hard time with lettuce and vegetable, How do you keep thinks from getting water logged?
Carolyn Shearlock says
Lettuce tends to bruise easily and does not do well when you’re traveling. Try using Napa Cabbage instead.
You’re on the right track with the cooler, but here’s an even better way to do it: Using a Cooler for Food

Sarah says
I buy gem lettuce, or others that have a stalk then store them with the stalks in a jar of water
Mitch Berger says
Can anyone please advise me… I have no fridge. I know a whole cabbage keeps a long time on the shelf, but then assuming one eats it in quarters, what is the best way to cut it so that the remainder will keep? Can the cut pieces still keep on the shelf? Many thanks.
Carolyn Shearlock says
Cut it any way you want and yes, the cut pieces can be left on the shelf. If the edge gets black, just cut it off.
Mitch Berger says
Wonderful! Thank you so much for your reply.
Tami says
We use up our cabbage by peeling the leaves rather than cutting it.
Also have found that romaine lettuce holds up fairly well. This may be the reason that it was just about the only lettuce we found in the Bahamas
Muchi says
“We use up our cabbage by peeling the leaves rather than cutting it.”
Excellent idea! So simple, and yet… I honestly didn’t think about doing that. Thanks so much!
althea brimm says
We just camped in Baja for a month with 2 large heads of cabbage, wrapped in paper towels & newspaper. I stored them in a hammock & we ate from them during the entire trip.

I’m staying in a hotel w/o a Fridge.
Very useful advice.
Simon Brookman says
Hi,
I tend to use a Food Dehydrator and or vacuum pack, as this not only makes to food last longer it also takes up less space.
Margie says
Hi everyone.
I just want to ask everyone how to preserve lettuce without fridge?
Carolyn Shearlock says
Lettuce does not last well without being kept cool. You can get a few days storage time by putting it in a bucket with a few inches of water. That’s one of the things I discuss in detail in Storing Food without Refrigeration, along with some great alternatives.
Brian says
Romaine lettuce lasts a LOT longer than regular lettuce, but it does need to be refrigerated, We buy a pack of 3 and it lasts us for 6 meals. Where regular lettuce may last a week if fresh, we have had romaine last 2-3 times longer as long as it is not manhandled.
Carolyn Shearlock says
The romaine that comes in plastic boxes (ugh – I hate plastic) seems to do better against bruising, too.
Sarah says
Awesome! We are getting used to using our ice box less and less because I can’t stand buying plastic bags of ice all the time. Plus we want to do a little more Pardey style cruising one day with no fridge. This article has been great to help me meal plan and I just bought your book for my Kindle!
Brad Carpenter says
“Do not store potatoes and onions together”
By “together”, do you mean in the same bin, the same shelf, or the same cupboard? Can I store them on separate shelves inside a pantry cabinet?
Carolyn Shearlock says
The further away the better, as they’ll last longer. I try to keep them in separate bins in a well-ventilated area.
James McGuffin says
My boat is a long range trawler with a RV size fridge. We are also whole food oil-free vegan so we carry a lot of grains, canned beans, tomatoes etc. we also try to eat as much fresh produce as possible. We eat virtually no processed food so we cook a lot, even our snacks. We tried the hammock route in the north while doing the inside passage and it worked pretty well. When coming from Hawaii to Seattle the hammocks swung to much for my liking and even bruised some of the produce. I noticed my clothes and other items rode out the storms in a safe, low position drawers.
I took some air circulation material commonly used under mattresses and lined the bottom and sides of several drawers. Placed my produce in the drawers and filled in any voids with certain clean clothing or dish towels. I put some of my most used clothing in the hammocks at first but have now successfully got rid of a bunch of stuff I never use and basically done away with the hammocks. We were shocked at how much secure storage space was wasted on things we either did not need or could be harmed if struck by a bowling ball.
Great Book!
Cool
Jim says
Could not be harmed….😀
